rust-raytracer

A final project for Stanford's CS248 http://cs248.stanford.edu/winter20.

This 1024x1024 image with about 2.3 million triangles was rendered with 16 samples per pixel in about 39 seconds (generating the BVH tree took about 27 seconds) on a 4 core i5-6600K CPU. Thanks to the Stanford Computer Graphics Laboratory for providing these models at https://graphics.stanford.edu/data/3Dscanrep.

Running

Use cargo to build, test, and run the code. For optimal performace, use the release build. The following command will render a basic scene to out.png with size 1024x1024.

#cargo run --release -- <args>
cargo run --release -- -f out.png -w 1024

To print useful timing information, set the environment variable RUST_LOG.

RUST_LOG=debug cargo run --release
